2 Corinthians 9:8 And God is able to make all grace abound toward you; that ye, always having all sufficiency in all things, may abound to every good work:
There’s never a shortage of the grace of God---grace for our spiritual ministries, our material and physical needs. If God’s grace is sufficient to save us, surely it’s sufficient to keep us and strengthen us in times of suffering.
God permits us to become weak so that we might receive His strength. This is a continuous process. The Apostle Paul prayed three times for The Lord to remove his thorn in the flesh.
2 Corinthians 12:9 And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. . . . .
Whenever you are going through suffering, spend extra time in the Word of God, and you can be sure He will speak to you. God’s grace is sufficient for your need.
